warez? ALEX WASLEEF, or orriorieo, ILLINOIS f HERRINGBON-E. procaine Application filed February 1929. Serial No. 341,352;

This invention relates to improvements in interlocking flooring and more particularly to mosaic flooring of the type commonly known as herringbone, which is usually but not always, laid on mastic or similar composition.

The principal object of the invention is to 20 tails of the flooring pieces as they are arranged for fitting together. I

Figure 3 is an enlarged detail view showing one end of one of the flooring pieces, and

Figure tis an enlarged detail showing an- I-other end ofone of the flooring pieces.

Referring to details shown in the drawings, the flooring is made up ofa seriesof flooring pieces arranged inv herringbone pattern, as shown in Figure '1. The pieces are of the vided with interlocking tongue and groove connections at abutting ends so as to hold the joints from lateral separation at these points after the flooring is laid.

In the embodiment illustrated herein, I

provide two setsof pieces generally similar in construction but with slightly difiering'arrangement of interlocking devices at thelr op- 7 posite ends so as to fit with abutting pieces.

One series of pieces is indicated at .10, 10 and the other series at 11, 11, each seriesbeing arranged so that all of them extendin the same direction, and at a 90 angle'to the other series. I

' Referring to theipieces forming one of the series, as for instance series 10, 10, each piece is provided with a tongue 12 along the ma or portion of its length and a groove '13 along the opposite side thereof. I A tongue 14 is also provided along substantially oneh'alf of familiar tongue and groove type, but are pro-,

one end of said pieceand a groove 15 in sub- '--stantially corresponding position at the opposite end of said piece 10. The pieces 11, 11 are similar to the pieces 10, 10 but with the position of the slots and grooves at the ends of the pieces in reversed order, i. e., at mutually oppositeends of the pieces, if the two pieces were arranged in parallel tongue-to-groove relationship witheach other. Details of the end grooves and tongues of pieces 11, 11 are shown in Figs. 3 and 4 respectively.

"As seen in the drawings, the series 10 and 11 are laid in end-to-side relationship with each other so that the tongue 14 of any series 10 piece fits into a groove 13a and engages stop 13?) on the adjacent side of the abutting series'll piece. Groove 15' at the opposite end of the same serles 10 piece will receive a relatively short tongue 16a in alignment with the maintongue 12a ofthe next piece of grouplL' 7 f I The pieces of groupll have similar endto-side interlockingengagement with the pieces 10-, by means of tongues 14:66 and grooves 15a, as'shown.

A further interlockingengagement is provided between adjacent pieces of the same series by providing stops 17 and 17d respectively in grooves 13 and 13a, to beengaged by the endsof tongues 12 and 120, as shown in the drawings. Thisv arrangement restrains longitudinal displacement of ad acent pieces ofthe same group ineither CllI'GCtlOll byreason of the stops 1? at one end of the grooves 13 and 13a, and stops 13?) at the opposite ends.

The arrangement above described issuch that the end of each piece is interlocked so as to restrain lateral movement of the abutting piece, and where all the pieces are so interlocked they are mutually held so as to elimi 'nate spreading at the joints after they are once laid in place.

7 I claim as-my invention:

. 1. Herringboneflooring comprising each having along and short tongue on one side and a groove on the opposite side, and a, relatively short tongue on one end and a short groove on the opposite end, said short tongue and groove both being disposed ad acent the same side of the piece,and having mutuallypieces interlocking engagement respectively with the side groove and the short side tongues of abutting pieces to restrain relative lateral movement of said abutting pieces in at least one direction,

Herringbone flooring comprising pieces each having a long and shorttongue on one side and a'groove on theopposite side, a

tongue substantially one-half the length of one end and a groove substantially one-half the length of the opposite end, said last named tongue and groove both being dis posed adjacent the same side of the piece, and having mutually interlocking engagement'respectively with the side groove and the short side tongues of-abutting pieces. 7 3

8. Herringbone flooring comprising two sets of pieces each having a long. and short tongue and groove on opposite side, a tongue extending a part of the length of one end; and a groove extending a part of the length of the oppositeend, the end tongues and grooves of the tWo sets being on mutually. opposite ends, and the end tongues and grooves of each set adapted to have interlocking engage- V ment, respectively, with the side grooves and 7 short tongues of abutting pieces of the other set.

' 4. Herringbone flooring colnprising'pieces each having a long and short tongue and groove on opposite side, and a relatively short tongue on one end and a short groove on the opposite end, said short tongue and groove having mutually lnterlocklng engagement respeetively Withihe side groove and short tongues of abutting pieces to restrain relative lateral movement of said abutting pieces in at least one direction, and stops in said side grooves engaged by the side tongues on laterally adjacent pieces restrainingrelative longitudinal movement therebetween;
